What does SLUDGEM stand for?

• A. Salivation; Lacrimation; Urination; Defecation; Gastrointestinal cramps; Emesis; Muscle Twitch
• B. Salivation; Lacrimation; Urination; Defecation; Gastric upset; Emesis; Muscle Tremor
• C. Salivation; Lacrimation; Urination; Defecation; Gastrointestinal upset; Emesis; Muscle Contraction
• D. Sweating; Lacrimation; Urination; Defecation; Gastrointestinal cramps; Emesis; Muscle Twitch

Answer: (A)

This item tests your recall of SLUDGEM, the mnemonic for signs of cholinergic excess such as from organophosphate poisoning or anticholinesterase exposure. The muscarinic effects drive production of secretions and smooth-muscle activity, leading to Salivation, Lacrimation, Urination, and Defecation, plus Gastrointestinal upset or cramps and Emesis. The M stands for Muscle Twitch, reflecting nicotinic receptor stimulation that can cause fasciculations. Sweating isn’t typically included in the SLUDGEM set, and variations like Tremor or Contraction describe different nicotinic presentations. The best choice lists Salivation, Lacrimation, Urination, Defecation, Gastrointestinal cramps, Emesis, and Muscle Twitch, matching both the muscarinic and nicotinic components of cholinergic excess.
